“Using official Croatian census data as a reference, [the researchers] analysed three global population datasets across seven Croatian cities to investigate how population allocation differs between built-up and non-built-up areas.
Although the datasets often produced similar population totals, their spatial allocation differed substantially. GHS-POP concentrated over 1 million more inhabitants within built-up areas, while WorldPop allocated approximately 290,000 more inhabitants to non-built-up land-cover classes, demonstrating how similar population totals can mask substantial differences in spatial population patterns.
The question is not only how many people are estimated, but also where the model places them…”

(1) Starting in 1964 Halle-Neustadt was created as a planned city in the german democratic republic. The intention was to provide housing for the workers of the nearby chemical plants.
At its peak in the 1980s Halle-Neustadt housed more than 90,000 people. However, after the german reunification half of the population left the city, reaching a low point of 45,025 inhabitants in 2015. In consequence many apartments and buildings were left empty.

Die Immobilienwirtschaft hätte es wohl gerne anders: Aber aus neuen @StatistikNord-Zahlen geht hervor, dass #Hamburg 2020 erstmals schrumpfende Stadt ist. Seit Januar sank die Bevölkerungszahl um ca. 2500 Menschen.
